St. Mary's Church in Sydney is close to Sydney Sky Tower and can be reached on foot. The church building is old and magnificent. Its contents are more dazzling. The church is large and there are many seats for worship. Tourists can visit it free of charge. But don't disturb the worshippers. It's really worth visiting. It seems that there is a donation box. I don't have any donations, so I don't remember it completely. Weekly comments, there is a park across the street, where many people play.
